The Australian comedian looked “ghe-bel” fabulous as she sat next to Conan O’Brien on Wednesday night’s Conan. The actress polished her look with a treasured family heirloom: a gold, bedazzled “B—h” necklace.

Aside from her retro outfit, Wilson also revealed that when it comes to learning “authentic” American English, she looks to Honey Boo Boo Child to help her with her pronunciation.

But how does Wilson practice her American accent?

“I watch a lot of reality shows because I want a real, genuine American accent,” she told O’Brien. “I watch Real Housewives of Beverly Hills. I’ve been watching a lot of Honey Boo Boo lately… because I do want my accent to be authentic when I do movies. I watch them and repeat them when they talk, and then eventually, hopefully, you learn through osmosis.”

Wilson, whose breakthrough role was playing Kristen Wiig’s looney roommate in 2011’s Bridesmaids, stars as the bride-to-be in the raunchy indie flick, Bachelorette, starring Kirsten Dundst. The fresh-faced actress also stars in the upcoming a cappella comedy Pitch Perfect, out in theaters Oct. 5.
